Chimps Held in Captivity for 30 Years Play in the Sun for the First Time

This is the moment a group of chimpanzees sees daylight for the first time in 30 years - after being locked in cages for medical testing.
The animals hugged each other in delight before they took their first steps outside.
The outing marked the end of a 14-year bid to re-integrate the 38 primates after they spent most of their lives cooped up inside.
